Cyclone Classification Catagories

How are cyclones classified? The more common scale is the one for measuring typical likely damage. This is based on the Saffir-Simpson Hurricane Scale Category Wind gust speed/ Swell Damage 1 less than 125km/h 1.2-1.6m milddamage 2 126-169km/h 1.7-2.5m significantdamage to trees 3 170 - 224km/h 2.6 -3.7 structuraldamage, power failures likely 4 225 - 279 km/h 3.8-5.4 most roofing lost 5 more than 280 km/h more than 5.4m almost total destruction Cyclones are classified based on information from satellite images and uses a scale called the Dvorak Number going from 0 to 8.
